The term "eq" is likely a typo or shorthand for "EQ," which stands for "Emotional Quotient." It refers to the ability to understand, evaluate, and manage emotions in oneself and others. An individual with a high EQ is typically good at empathizing with others, handling social situations adeptly, and managing their own emotional states effectively.
The term "Emotional Quotient" was derived from the concept of "Intelligence Quotient" (IQ). "Emotional" relates to emotions, from the Latin word "emovere," meaning "to move out, remove." "Quotient" comes from the Latin "quotientem," meaning "one who is being divided."
